1. Chiyambi cha Diquat

Diquat ndi mankhwala a herbicide achitatu otchuka padziko lonse lapansi pambuyo pa glyphosate ndi paraquat.Diquat ndi bipyridyl herbicide.Chifukwa ili ndi atomu ya bromine mu dongosolo la bipyridine, imakhala ndi zinthu zina zadongosolo, koma sizingawononge mizu ya mbewu.Itha kuchitidwa m'mwamba kudzera mu phloem ya mbewu, motero ndi yabwino kuposa glyphosate.ndi glufosinate amapha namsongole mwachangu komanso moyenera.Mukagwiritsidwa ntchito m'minda, namsongole wofukulidwa nthawi zambiri amaphedwa mbewu isanabzale komanso ikatha kumera, kapena kupopera mbewu mankhwalawa molunjika m'mizere kumagwiritsidwa ntchito kumapeto kwa nthawi yophukira.Panthawi imodzimodziyo, diquat imakhalanso yolumikizana ndi desiccant ndipo ingagwiritsidwe ntchito ngati chofota / kucha musanayambe kukolola komanso ngati desiccant kwa mbewu zambewu.

2. Ntchito mbewu zosiyanasiyana diquat

Diquat ndiyothandiza kwambiri kuposa paraquat ndipo imakhudzanso udzu wamasamba otakata.Ndioyenera kupalira musanafesedwe m'minda yosalimidwa komanso yosalimidwa, m'minda ya zipatso, ndi kupalira pakati pa mizere ya mbewu.Atha kugwiritsidwanso ntchito kukolola mbewu monga soya, mbatata, ndi thonje.Yoyamba imayambitsa kufota ndi kufota.

3. Ubwino wa diquat ndi chiyani?

①. Zochita mwachangu: Diquat ndi paraquat onse ndi mankhwala a bipyridyl herbicides ndipo ali ndi mawonekedwe ofanana potengera momwe amapangira herbicide.Imapha udzu mwachangu kuposa paraquat.Zimayamba kugwira ntchito tsiku lomwelo, ndipo udzu umayamba kufa mkati mwa maola 24.Mvula imagwa ola limodzi pambuyo popopera mankhwala, zomwe zimakhala ndi mphamvu zochepa pakuchita bwino.

②.Chitetezo chabwino, kuteteza madzi ndi nthaka: Ngakhale kuti diquat ili ndi zinthu zina mwadongosolo, siiwononga mizu ya mbewu, ndipo imapha anthu.Chifukwa chake, diquat imapitilizabe chitetezo cha paraquat popanda zotsalira komanso zowopsa zoyendetsa.Popeza kuti udzu wa adani supha mizu, umathandizira kusungira madzi ndi nthaka, ndipo zitunda za m’munda sizovuta kugwa.

③.Mphamvu yapadera pa namsongole wa masamba otakata: Diquat imakhala ndi mphamvu yowongolera bwino kuposa glufosinate pa udzu wosamva, makamaka udzu.

④.Kutsika kwa kutentha: Kutentha kukakhala kotsika kuposa 15 ℃, kupalira kumakhala kopindulitsa kuposa glufosinate-ammonium.

4. Momwe mungagwiritsire ntchito Diquat moyenera?

①.Kupalira m'chipululu: Ma glyphosate ena amatha kuwonjezeredwa moyenera, ndipo kubwezeredwa kwa namsongole pambuyo pake kudzachepetsedwa kwambiri.Ponena za mlingo wake, mutha kuyesa kaye pagawo laling'ono malinga ndi momwe udzu ulili.

②. Kwa udzu womwe umalamulidwa ndi Gramineae, mutha kuwonjezera quizalofop, clethodim, flufenofop, ndi zina zambiri kuti muwonjezere kuchuluka kwa herbicidal, ndipo nthawi yowononga udzu ifika pafupifupi masiku 30.

③.Popeza diquat ndi yopha anthu, popopera mankhwala a diquat, iyenera kupopera bwino komanso mofanana.Zolowera monga organic silicon zitha kuwonjezedwa kuti pamwamba pa udzuwo masamba azitha kulumikizana ndikuyamwa diquat kuti akwaniritse zotsatira zabwino.Zabwino zowononga udzu.

④.Pothirira diquat, musagwiritse ntchito madzi a mtsinje a turbid kuti asachepetse mphamvu ya mankhwalawa.

⑤.Yesani kugwiritsa ntchito mankhwala mame akayamba nthunzi m'mawa.Pamene kuwala kwa dzuwa masana, kukhudzana zotsatira adzakhala zoonekeratu ndipo zotsatira adzakhala mofulumira.(Pakani mankhwala usiku kusanakhale mame, kuti mankhwala azikhala othandiza kwambiri)
